gold: Add sparc IFUNC support to Gold.
elfcpp/
* sparc.h (R_SPARC_JMP_IREL): New relocation.
gold/
* sparc.cc (class Target_sparc): Add rela_ifunc_.
(Target_sparc::Target_sparc): Initialize new field.
(Target_sparc::do_plt_section_for_global): New function.
(Target_sparc::do_plt_section_for_local): New function.
(Target_sparc::reloc_needs_plt_for_ifunc): New function.
(Target_sparc::make_plt_section): New function, broken out of
make_plt_entry. Use ORDER_NON_RELRO_FIRST for ".plt".

(Target_sparc::rela_ifunc_section): New function.
(Target_sparc::plt_section): Remove const.
(Output_data_plt_sparc): Update declarations. Define Global_ifunc
and Local_ifunc types. Add global_ifuncs_, local_ifuncs_, ifunc_rel_,
and ifunc_count_ fields.
(Output_data_plt_sparc::Output_data_plt_sparc): Initialize new fields.

(Output_data_plt_sparc::plt_index_to_offset): New function.
(Output_data_plt_sparc::set_final_data_size): Use plt_index_to_offset
and entry_count.
(Output_data_plt_sparc::do_write): Use first_plt_entry_offset and
entry_count.
(Target_sparc::Scan::get_reference_flags): Add R_SPARC_IRELATIVE and
R_SPARC_JMP_IREL to switch.
(Target_sparc::Scan::check_non_pic): Likewise.
(Target_sparc::Scan::local): Handle IFUNC symbols.
(Target_sparc::Scan::local): Likewise.
(Target_sparc::Relocate::relocate): Likewise, use plt_address_for_global
and plt_address_for_local.
(Target_sparc::do_finalize_sections): Call emit_pending_ifunc_relocs.
Define __rel_iplt_start and __rel_iplt_end if doing a static link.
